The air pressure source in pressure tanks is supervised in accordance with which NFPA code?

• A. NFPA 70
• B. NFPA 72
• C. NFPA 13
• D. NFPA 25

Answer: (B)

Maintaining an alarm when the air supply for a pressure tank changes is about signaling and notification, not just the physical piping. The air pressure source in a pressure tank for a water-based system needs to be monitored so that any drop in pressure can alert building personnel and trigger appropriate action. That kind of supervision—monitoring a critical equipment condition and signaling it to the fire alarm system—is covered by NFPA 72, the Fire Alarm and Signaling Code. It specifies how supervisory signals for equipment status, like a low air pressure condition, should be detected and reported to the fire alarm control panel. NFPA 13 deals with how sprinkler systems are installed (including dry pipe configurations), but not the signaling rules. NFPA 25 covers inspection, testing, and maintenance of water-based systems, which would address periodic checks but not the specific signaling requirements. NFPA 70 is the National Electrical Code, which governs electrical installation in general but doesn’t provide the supervision requirements for the air pressure signaling itself.
